Walkerduct Pro Series Presets:
1. Use a Walker insert finder (Cat. No. 480) or other electronic
locator to find center of preset. Cut and remove carpeting or
tile over preset. (Carpet may be saved for later abandoning.)
Chip out concrete exposing mudcap.
NOTE: If presets are more than 1/2" [12.1mm] below concrete, use of a hammer
drill with 1/2" chisel is recommended. Be careful not to damage preset!
2. Remove Mudcap: (See Figure 1).
A. Strike blade of screwdriver or 1/4" [6.4mm] cold chisel
along side of mudcap as shown. Top edge of mudcap
will deflect inward.

between preset wall and deflected edge of mudcap,
or, use pliers to grab edge of cap and lift out.
